Description:

Laptop has a non-free boot firmware. The WiFi card, QCA6174, has an open-source driver available but requires non-free firmware to run. The WiFi card is physically impossible to replace on this model and will require a USB dongle. I did not test bluetooth functionality. Everything else seems to work fine with all free software.
